In drawing, when the quality of a single line changes from thick to thin, it is referred to as calligraphic. Calligraphy is an art that is associated with writing. It involves designing and executing a lettering using a broad tip instrument or a brush. Pens that are used for this uses nibs which can be pointed, round or flat.
I believe that would be speed. Velocity on the other hand would indicate speed AND direction
Answer: The entangled players would move with a speed of 0.2 m/s in the direction direction of the motion of second soccer player.
Explanation:
From law of conservation of momentum,
Initial momentum of the closed system = final momentum of the closed system
Since, no external force is acting on the players, total momentum would be conserved.
m₁u₁+m₂u₂=(m₁+m₂)v
where, m₁ is the mass of one soccer player = 40 kg
u₁ is its initial velocity before collision = 4 m/s
m₂ is the mass of the other soccer player = 60 kg
u₂ is the initial velocity before collision = - 3 m/s (∵opposite direction)
After collision, the two players get entangled and hence move with the same final velocity v.
40 kg × 4 m/s - 60 kg × 3 m/s = (40 kg + 60 kg ) v
160 kg m/s - 180 kg m/s = 100 kg v
v = -0.2 m/s
Hence, the entangled players would move with a speed of 0.2 m/s in the direction direction of the motion of second soccer player.
Answer:
A.
B.
C.
Explanation:
The capacitance of a capacitor is its ability to store charges. For parallel-plate capacitors, this ability depends the material between the plates, the common plate area and the plate separation. The relationship is
is the capacitance, is the common plate area, is the plate separation and is the permittivity of the material between the plates.
For air or free space, is called the permittivity of free space. In general, where is the relative permittivity or dielectric constant of the material between the plates. It is a factor that determines the strength of the material compared to air. In fact, for air or vacuum, .
The energy stored in a capacitor is the average of the product of its charge and voltage.
Its charge, , is related to its capacitance by (this is the electrical definition of capacitance, a ratio of the charge to its voltage; the previous formula is the geometric definition). Substituting this in the formula for ,
A. Substituting for in ,
B. When the distance is ,
C. When the distance is restored but with a dielectric material of dielectric constant, , inserted, we have
